BRYSTON phono step up trans TF-1 superb unit In flawless condition

. I am selling a now very RARE hard to find Step up transformer made by Bryston. This unit was the preferred reference step up in the Reference system of UHF and Stereophile for over 20 years , is an extremely well built unit which was based on their previous model which was designed and built by Mitchell Cotter. With many design improvements and modifications to the original design. This is leaps and bounds ahead of the Mitchell Cotter version and you can clearly hear the achievements the design changes made. PLEASE read,
1. The eliminated the external phono cable which was a weak link
2. High quality RCA in's and outs let you use your Quality phono cable
3. improved mass and isolation with a heavier casing
4. 40% lower distortion then the original design
5. much lower noise floor
6. more attack and with better pace and punch! overall the much improved design is a real winner and an all ready amazing unit like the original Mitchell Cotter step up even better by refining its weaknesses .
PLEASE NOTE : I will ship this unit worldwide on a request basis to most countries as you know some country's can be problematic with custom's and overall the postal system. So please ask in advance, the TF-1 is Mint in my eyes and appears unused, I will rate it a 9/10 to avoid issues but I cannot find any faults what so ever and as mentioned appears IN NEW CONDITION. questions are welcome and I will pay the shipping in North America at my asking price, Sorry payment by paypal only but will consider a bank transfer, or in Canada Interact payment. Questions welcome and phone calls preferred ,Happy Listening, Daren 613 397 1839
